The child was in a car at a Morris Road office lot. The mother called to determine where the child was, and the father found him still in the car seat. The father then called 911.

Daytime temperatures Thursday hovered in the low teens. The child was bundled in warm clothes, and the car was sitting in the sun.

"The father drove from southern Rensselaer County to work so we're guessing he had the heat blasting," Winn said. That meant the car remained warm for some time after the car was parked.

The child was conscious and alert when found, police said.

The police were notified at 4:14 p.m.

Investigators have not yet decided whether to press legal charges so the father's identity is not being released. Child Protective Services has been notified, Winn said.

In 1994, Colonie had a similar case during hot weather where a child died.

The Clifton Park father pulled up to the Shaker Road Firehouse with his 5-month-old son in the car. He had accidentally left the child in the overheated car for almost 10 hours, police said at the time.
